Good grief! This sounds like "A Twist Of Sand", if anyone remembers it. I have travelled via Landrover and Jeep in many areas of Diamond Areas 1 and 2, and never in my wildest dreams did I experience 'quicksand'. This was almost fifty years ago and, like the old SWA cops we became fairly good drivers in the dunes and on the beach [when there was one]. Helicopters indeed; that's for sissies!

Welcome onto the Board Larry, keep 'em coming, I have taken the liberty of pasting your email to me in here...

Larry!! I remember the book, the author was Geoffery Jenkins and there was a film called 'A Twist Of Sand' with Richard Johnson, Honor Blackman, Jeremy Kemp, and I think at the end of the book the plot turned out to be OIL not Diamonds.

The book was much better than the film.

'On The Beach' by Nevil Shute a better film and a good author.

Geoffrey Jenkins visited Oranjemund in the 1950's to do his research for A Twist of Sand and my father Phil Bruce was asked to escort him through the mining areas. They spent several days together and Dad is mentioned in the books acknowledgments for the assistance he provided.

The Tellurometer was the first successful microwave electronic distance measurement equipment. The name derives from the Greek tellus, meaning Earth.

History:

The original Tellurometer, known as the Micro-Distancer M/RA 1, was introduced in 1959.[1] It was invented by Dr. Trevor Lloyd Wadley of the Telecommunications Research Laboratory of the South African Council for Scientific and Industrial Research (CSIR), also responsible for the Wadley Loop receiver, which allowed precision tuning over wide bands, a task that had previously required switching out multiple crystals.[2]

Methodology:

The Tellurometer emits an electronic wave: the remote station reradiates the incoming wave in a similar wave of more complex modulation, and the resulting phase shift was a measure of the distance travelled. The results appear on a cathode ray tube with circular sweep. This instrument penetrates haze and mist in daylight or darkness and has a normal range of 30-50 km but can extend up to 70km.[3]

Application:

The Tellurometer design yields high accuracy distance measurements over geodetic distances, but it is also useful for second order survey work, especially in areas where the terrain was rough and/or the temperatures extreme.

The MRB2 or Hydrodist was a marine version[3] that was used in coastal surveys and calibrating ships using other survey navigation systems.

Commercial exploitation:

Plessey, the British electronics company, formed a new subsidiary known as Tellurometer (Pty) Limited in the 1960's to manufacture the product and to develop and sell derivatives.[3] The Company subsequently introduced numerical displays, solid state transmitters, integrated circuits and eventually microprocessors for the product.

Plessey also supply Tellurometers for the mining industry. The unit is fitted on top of the man cage , or rock hoist - the signal is transmitted to surface , giving a precise reading of the position of the cage . Especially helpfull on the Automatic Coupe hoists like the ones supplied by Asia & AEG ..
